Description

[Detailed description of the invention] [Industrial field of application] This invention is for winding linear objects such as hoses and electric cords of power spreaders, gas or electric welding machines, etc. onto a winding drum as they travel. This invention relates to a winder for a linear body that can be wound or unwound.

[Prior art] Conventionally, as this type of winding machine, the
What is seen in the 20071 publication is that the winding drum is supported above the wheels and is in a high position, and
The winding drum has a structure in which a drive roller, which rotates by receiving rotational power from a running wheel, presses against the winding drum and is driven to rotate.

[Problems that the invention aims to solve] With such a structure, the center of gravity of the machine, which is mainly the weight of the winding drum, becomes high, which makes the machine unstable and poses a risk of tipping over. Maneuverability is also poor, and since the structure is such that the winding drum is only driven by pressure against the drive roller that receives rotational power from the running wheels, for example,
When winding a new hose around the winding drum or replacing a hose that has already been wound around the winding drum, you can conveniently wind the hose using external power while the machine is stopped. There is a problem that it cannot be done.

[Means for solving the problems] The present invention solves such problems and reliably winds up the linear object from the winding drum as the running wheels rotate while keeping the machine body stable. The hose can be pulled up and let out, and the hose can be easily wound up while the machine is stopped. Therefore, a linear body winding drum, which is located between the left and right running wheels and has a smaller diameter than the running wheels, is mounted coaxially with the running wheels, and one running wheel and the winding drum are connected to each other by power. Through an interlock release device that switches on and off transmission, the running rotation of the running wheels is interlocked to drive the winding drum, and a linear guide member at the front of the machine can be moved back and forth to the left and right. The winding drum and the guide member are arranged in a power transmission path that interlocks and connects the winding drum and the guide member, and drives the winding drum and the guide member with external power in a power transmission path that interlocks and connects the winding drum and the guide member. When the interlocking between one of the running wheels and the winding drum is released by the interlocking release device,
Only the winding drum and the guide member can be operated by an external drive device.

[Function] Therefore, when one of the running wheels and the winding drum are in a linked state due to the interlock release device, the winding drum is interlocked with the running wheel as the running wheel rotates, and the linear The body is guided by the guide member at the front of the machine body, and is wound up in an orderly manner on the winding drum, and is smoothly unwound from the winding drum. When the interlock release device is operated to the release state, it is possible to conveniently wind up a long linear body while the machine is stopped.

[Example] Next, the embodiment shown in the drawings will be described.

A chain 18 is hung between the front sprocket 47 fitted and fixed to the right end of the napier shaft 12 and the rear sprocket 10. A pin 49 is inserted in the diametrical direction inside the cylindrical metal 48 that is fitted and fixed to the right end of the napier shaft 12, and the crank type manual handle 1
The tip of the pin 9 is removably fitted into the cylindrical metal 48, and an engagement groove 50 into which the pin 49 can be fitted is formed in the tip.

Therefore, for example, when winding up the hose B on the ground, which is extended from a power sprayer (not shown) and connected to a winding machine far away, onto the winding drum 9 during a spraying operation, Figures 2 and 3
As shown in the figure, both drive wheels 8 are set to be forward of the axis 0, and the longer diameter side of the cam 39 is in contact with the outer end surface of the support shaft 4 in the direction shown by the imaginary line in FIG. When the cam 39 is rotated by the lever 39a and the friction plate 14 is brought into strong pressure contact with the friction plate 4a through the compression spring 35 by the pulling action of the rod 36, both drive wheels 8 are driven, and the aircraft moves in the direction indicated by the arrow. move forward in the direction

As the aircraft moves forward, the running wheels 2 and 3 that are in contact with the ground rotate, and in particular, the rotation of the running wheel 2 is caused by the drive and
The increased speed is transmitted to the driven sprocket 15 via the intermediate sprockets 2c, 17 and the chain 16, and this increased rotation is transmitted to the support shaft 4 via the one-way clutch 13, and from the support shaft 4 to the friction plates 4a, 14. ,
It is transmitted to the winding drum 9 via the pin 41. With the rear sprocket 10 of the support shaft 5 rotating at the same time together with the winding drum 9 rotating the napier shaft 12 via the chain 18, both guide members 11 are reciprocated laterally, so that the hose on the ground B is guided by both guide members 11 and wound up on the winding drum 9 in an orderly manner.

In that case, the distance traveled by one rotation of the running wheels 2 and 3 and the winding dimension of the hose B by one rotation of the winding drum 9 will be longer or shorter depending on their diameters, and the distance traveled by the winding drum 9 will vary. The effective diameter changes depending on the length of the hose B, and the winding dimension of the hose B by one rotation of the drum 9 varies. Therefore, the speed of the rotation of the running wheel 2 is increased by a speed-increasing transmission mechanism, and the transmission is transmitted to the winding drum 9. By rotating the winding drum 9 at an increased speed relative to the travel distance of the running wheel 2, the initial winding of the hose B is performed. In addition to approximately matching the take-up dimensions, correction of the take-up dimensions that gradually increase from the beginning to the end of the take-up of the hose B with respect to the take-up drum 9 can be done by pulling the hose B extended above the ground in accordance with the gradually increased take-up dimensions. However, this tensile force is applied to the friction plate 14 as resistance, and the support shaft 4 is rotated by sliding between the friction plates 14 and 4a.

In this way, the rotational speed of the winding drum 9 is reduced in accordance with the resistance, and the hose B can be wound to a length corresponding to the travel distance without forcibly dragging the hose B while winding it up and causing damage. will be held.

Conversely, when the hose B is fed out and placed on the ground, the handle 7 remains in the same position and the other drive unit A is rotated 180 degrees around the axis 0, as shown in Figures 2 and 3. As shown by the imaginary lines in Fig. 3, both drive wheels 8 are set so as to be deviated rearward from the axis 0, and when the machine is moved backward in the direction of the reverse arrow A, the running wheels 2 run in the reverse direction and the winding The drum 9 can rotate on its own axis due to the resistance of the hose B placed on the ground and can feed out the hose B.

At this time, since the accelerated reverse rotation of the sprocket 15 has a faster rotational speed than the rotation of the winding drum 9, that is, the support shaft 4, the one-way clutch 13, which is a one-way transmission mechanism, , the accelerated reverse rotation of the sprocket 15 is not transmitted to the support shaft 4, and the support shaft 4 freely rotates reversely in the reverse rotation direction within a range slower than the reverse rotation of the sprocket 15,
That is, the winding drum 9 can rotate.

As described above, the rotation of the running wheel 2 and the rotation of the winding drum 9 are synchronized by a rotation synchronization device consisting of a speed-up transmission mechanism, a one-way transmission mechanism, and a sliding transmission mechanism.

In this way, the winding drum 9 is connected to both running wheels 2,
3, the center of gravity of the aircraft can be lowered, making it possible to control the aircraft better without tipping over.Also, since the guide member 11 is placed at a low position in front of the aircraft, it can be positioned at a low position. The guide member 11 allows the hose B to be well guided and wound up in an orderly manner.

In addition, when winding up the hose B without moving the machine, use the interlock release device to move the lever 39a so that the short diameter side of the cam 39 contacts the outer end surface of the support shaft 4, as shown by the solid line in FIG. The cam 39 is rotated by the compression spring 35 against the friction plate 14.
By weakening the elastic force of the winding drum 9, the winding drum 9 can be set to rotate freely in the forward and reverse directions independently of the running wheel 2. In that state, the manual handle 19
At the same time, the tip of the engagement groove 5 is fitted into the cylinder metal 48.
0 into the pin 49 and rotate the napier shaft 12 with the manual handle 19, both guide members 11
Since the winding drum 9 can be rotated while reciprocating in the lateral direction, the hose B can be manually wound in an orderly manner while the machine is stopped.

Incidentally, with the same structure, electric cords and other linear objects can be similarly wound onto the winding drum 9 and let out.

In addition, although the manual handle 19 is constructed so as to be able to be inserted into and removed from the tube metal 48 fixed to the end of the napier shaft 12, it may be of a regular configuration. However, it is sufficient that the external drive device is interposed in a power transmission path that interlocks and connects the winding drum 9 and the guide member 11.

[Effect of the invention] As described above, the present invention makes both running wheels 2 and 3 and the winding drum 9 coaxial, and the guide member 1 is installed at the front of the machine body.
1, the center of gravity of the aircraft can be made as low as possible, and the aircraft can run stably without falling over.

In addition, since the winding drum 9 and one of the running wheels 2 can be made free, if only the winding drum 9 and the guide member 11 are rotated by an external drive device, it is convenient to use external power while the machine is stopped. Therefore, when assembling or replacing the linear body, winding can be done quickly and easily on the winding drum 9, and this feature makes it suitable for use as a winding machine with good operability. have
